ChatGPT drops text limits for free users
OpenAI removed message caps on text chats for free and Go users and shipped GPT-5.6 Luna and an upgraded GPT-5.6 Sol, cutting factual errors 62% and 68%.
OpenAI is removing message limits on text-based ChatGPT chats for everyone, including free users, and making GPT-5.6 Luna the new default model for free and Go tiers, with a “Think” button available for harder questions. Plus and Pro subscribers get an upgraded GPT-5.6 Sol described as giving “more compact and robust answers,” plus a thinking slider to dial reasoning depth up or down. OpenAI says factual errors dropped 62% for GPT-5.6 Luna and 68% for GPT-5.6 Sol compared with the prior model generation.
What it means for you
Free-tier ChatGPT has always been the version most likely to hit a wall mid-task, whether that’s a rate limit interrupting a long conversation or a weaker model producing answers you had to double-check. Removing the text-chat cap and shipping a materially more accurate default model narrows the gap between free and paid for anyone whose usage is mostly text rather than image, voice, or heavy agentic work. If your team has been paying for seats mainly to avoid free-tier limits, this is worth a re-check: unlimited text on a lower-error-rate model may cover more of your actual usage than it did last month. It builds on the same access-expansion pattern behind OpenAI lifting other API limits across the industry as competition on cost and availability keeps intensifying, not just on raw capability.
